10-Bit DAC in MSOP

DESCRIPTIO

FEATURES

The LTC^®1661 integrates two accurate, serially addres-

sable, 10-bit digital-to-analog converters (DACs) in a

single tiny MS8 package. Each buffered DAC draws just

60µA total supply current, yet is capable of supplying DC

output currents in excess of 5mA and reliably driving

capacitive loads up to 1000pF. Sleep mode further re-

duces total supply current to a negligible 1µA.

■

Tiny: Two 10-Bit DACs in an 8-Lead MSOP—

Half the Board Space of an SO-8

Micropower: 60µA per DAC

■

Sleep Mode: 1µA for Extended Battery Life

Rail-to-Rail Voltage Outputs Drive 1000pF

Wide 2.7V to 5.5V Supply Range

Double Buffered for Independent or Simultaneous

■

DAC Updates

Reference Range Includes Supply for Ratiometric

Linear Technology’s proprietary, inherently monotonic

voltage interpolation architecture provides excellent lin-

earity while allowing for an exceptionally small external

form factor. The double-buffered input logic provides

simultaneous updatecapabilityandcanbeusedtowriteto

either DAC without interrupting Sleep mode.

0V-to-V Output

■

Reference Input Has Constant Impedance over All

Codes (260kΩ Typ)—Eliminates External Buffers

3-Wire Serial Interface with

Schmitt Trigger Inputs

Differential Nonlinearity: ≤±0.75LSB Max

Ultralow supply current, power-saving Sleep mode and

extremely compact size make the LTC1661 ideal for

battery-powered applications, while its straightforward

usability, high performance and wide supply range make

it an excellent choice as a general purpose converter.

APPLICATIO S

■

Mobile Communications

Digitally Controlled Amplifiers and Attenuators

Portable Battery-Powered Instruments

Automatic Calibration for Manufacturing

For additional outputs and even greater board density,

please refer to the LTC1660 micropower octal DAC for

10-bitapplications. For8-bitapplications, pleaseconsult

the LTC1665 micropower octal DAC.
